There is a classic pair of VTL TT-25 Tiny Triodes for 875 which is a great price. You could even re-tube with NOS tubes from Andy at VintageTubeServices and be near your 2K budget. Also there is a pair of Music Metre silver interconnects (retail 400) that will do what you are looking for at 198 and you get a pair of Signature coppers for free.
The Unison looks interesting.
